These were installed in the front and rear doors of a 2007 Inifinty M35 with the base radio. I have been complaining to the auto dealer that there was no depth or clarity to the sound. The dealer rep said no one changes out the Infinity system because they are so good. I talked to installation shops and some said don't change the speakers because they are of such good quality add a amp, others said change the speakers. Confused I called Polk help and was advised to try the speakers first. These MM651 speakers make my system awesome. I play the radio at low to medium volume and the sound is superior, I now hear music with great claity and definition. The sound is now better with the basic stock Infiniti radio than the ultra premium Bose that I have in my Audi A6. I am totally satisified and really appreciate the help from the Polk reps.
